Definitions

  • the present invention concerns a drive train of a motor vehicle with an internal combustion engine and with an electric motor.
  • hybrid architectures of a drive train of a motor vehicle which combine an internal combustion engine and an electric motor to ensure an efficient drive of the motor vehicle.
  • three different levels of hybridization are distinguished which differ in relation to the contribution of drive torque supplied by the electric motor.
  • an electric motor for so-called micro-hybrid vehicles, usually an electric motor is provided for an automatic start-stop system and a braking energy recovery system to charge a comparatively small starter battery.
  • the electric motor is not used to drive the vehicle.
  • the electric motor in contrast supports the internal combustion engine to increase the power. Also with a suitable design of the drive train, the energy occurring during a braking process can be partly recovered in a generator mode of the electric motor.
  • full hybrid vehicles are able to be driven completely by the electric motor.
  • the internal combustion engine merely drives an electric generator which supplies the electric motor with the electrical energy and/or charges a battery. Therefore smaller-dimensioned internal combustion engines can be used than in motor vehicles with comparable performance levels.
  • the internal combustion engine can be operated in an efficient operating state as power peaks can normally be covered by extracting energy from the battery.
  • Hybrid architectures are known in which an electric motor and an internal combustion engine are connected together or with the drive train via one or two clutches.
  • a disadvantage, in particular in architectures with two clutches, is the complex design of the clutches and the functional and geometric integration of the electric motor in the drive train. Also control of the system is comparatively complex.
  • an object of the present invention to provide a drive train which fulfils the functionality of a mild hybrid and, for at least part of the time, also allows purely electric drive of the vehicle.
  • the components necessary for said functionalities can easily be integrated in a conventional drive train of a motor vehicle with only an internal combustion engine.
  • a drive train of a motor vehicle with an internal combustion engine, with an electric motor and with a coupling device which comprises a first coupling unit allocated to the internal combustion engine and a second coupling unit allocated to the electric motor and by means of which the internal combustion engine and/or the electric motor can be connected for drive purposes with a common drive shaft to drive at least one wheel of the motor vehicle, wherein the first coupling unit and the second coupling unit are separate components which can be coupled together automatically by a clutch depending on a difference between a rotation speed of the internal combustion engine and a rotation speed of the electric motor.
  • the internal combustion engine and the electric motor can be connected with the drive shaft via separate coupling units, so that different configurations of the drive train can be provided in different drive situations.
  • both the internal combustion engine and the electric motor can be connected with the drive shaft selectively and independently of each other.
  • the coupling device is formed such that the internal combustion engine can only be coupled with the drive shaft when the electric motor is connected with the drive shaft via the second coupling unit.
  • the drive train according to the invention can be operated reliably. It ensures that the coupling units are coupled without external intervention when certain operating parameters are present.
  • the coupling of the coupling units takes place depending on a difference between a rotation speed of the internal combustion engine and a rotation speed of the electric motor.
  • the internal combustion engine and the electric motor are coupled together when suitable conditions are present, for example in order then to be able to contribute jointly to the drive of the vehicle.
  • both the working power of the internal combustion engine drives the vehicle and the generator operation of the electric motor generates electrical energy which is used to operate ancillary assemblies and/or to charge an energy accumulator.
  • the electric motor can easily be integrated in a conventional drive train since only the coupling device and the electric motor need be inserted.
  • the former can for example be integrated in a starter element and/or in a torsional vibration damper or at least arranged in the physical vicinity of said components.
  • the clutch is formed such that the first coupling unit is coupled for drive purposes with the second coupling unit when the rotation speed of the internal combustion engine is substantially equal to or greater than the rotation speed of the electric motor.
  • a coupling between the first and second coupling unit is created only when the internal combustion engine has at least the same rotation speed as the electric motor.
  • the first coupling unit, the second coupling unit and/or the clutch can be arranged coaxially. Alternatively or additionally it can be provided that the internal combustion engine and/or the electric motor are arranged coaxial to the first coupling unit and the second coupling unit.
  • a compact construction of the drive train results when the rotation axis of the electric motor is arranged offset to the rotation axis of the internal combustion engine.
  • the clutch is an overrun device.
  • the overrun device allows selective coupling and decoupling of the two coupling units as a function of the difference in rotation speed between the electric motor and the internal combustion engine. In other words a coupling between the coupling units takes place only when certain load conditions are present.
  • overrun devices In principle a multiplicity of different construction types of overrun devices are known which can be selected as required.
  • the first coupling unit can be a first flywheel and the second coupling unit can be a second flywheel.
  • the first flywheel and the second flywheel have different moments of inertia, wherein in particular the moment of inertia of the second flywheel is less than the moment of inertia of the first flywheel.
  • This design takes into account the fact that the rotational irregularities occurring in connection with the operation of the internal combustion engine are usually greater than those occurring on operation of an electric motor. The need for damping of torsional vibrations is therefore greater for the internal combustion engine than for the electric motor, so the corresponding flywheel has a higher mass inertia than that of the electric motor.
  • the lower mass inertia of the second flywheel brings the advantage that less energy must be applied for its acceleration.
  • the electric motor can be coupled for drive purposes with the second coupling unit via a belt drive, a chain drive or a gear connection. The same applies accordingly to the coupling of the internal combustion engine with the first coupling unit.
  • the first coupling unit and/or the second coupling unit can be connected with the drive shaft via a starter element, in particular a clutch, and/or a rotational vibration damper device.
  • the coupling units form function elements of the rotational vibration damper device. For example depending on operating mode, either individually or in coupled state, they form one of the centrifugal masses of a dual-mass flywheel.
  • a constructionally simple integration of the coupling device in a conventional drive train can be achieved if the coupling device is arranged between the internal combustion engine and a translation gear of the drive train.
  • the drive train can comprise a separate starter motor to start the internal combustion engine, so that the internal combustion engine can be started independently of operation of the electric motor.
  • the starter motor is connected with the internal combustion engine via the first coupling unit.
  • the first coupling unit as a flywheel, a starter ring gear can be provided thereon which engages with a gear wheel coupled with the starter motor.
  • the electric motor can be operated as a motor or as a generator.
  • electrodynamic braking can also be provided, i.e., in overrun mode of the motor vehicle, that is, when neither the drive pedal nor the brake pedal are activated, a generator mode of the electric motor can be used to generate electrical energy.
  • the internal combustion engine is decoupled in this state as its rotation speed in said situation usually lies below the rotation speed of the drive shaft.
  • the electric motor can be connected for drive purposes directly or indirectly with ancillary assemblies in order to operate these.
  • FIGS. 1 to 6 illustrate various embodiments of the drive train in accordance with the invention.
  • FIG. 1 illustrates a drive train 10 a with an electric motor 12 and an internal combustion engine 14 .
  • the electric motor 12 is connected via a converter 16 with a battery 18 and, depending on operating state, can charge the battery 18 or extract energy therefrom in order to drive the motor vehicle.
  • the drive train 10 a serves drive wheels 20 of an axle of the motor vehicle.
  • the wheels 20 are connected with a drive shaft 26 via a differential gear 22 and a translation gear 24 .
  • a belt pulley 30 is provided which is coupled with an output shaft 28 of the electric motor 12 and is also coupled via a belt 32 with a flywheel 34 .
  • the flywheel 34 is selectively connected via a starter element 36 with a torsional vibration damper 38 coupled to the drive shaft 26 .
  • the necessary drive moment is provided solely by the electric motor 12 and is transmitted to the flywheel 34 via the shaft 28 , the belt pulley 30 and the belt 32 .
  • the starter element 36 With the starter element 36 closed, the vehicle can be moved in the selected gear stage of the translation gear 24 . If now additional drive torque is required at higher speeds, the internal combustion engine 14 is connected. To this end, a starter motor 40 is activated which sets the internal combustion engine 14 running. As the internal combustion engine 14 and the flywheel 34 are not permanently coupled, the internal combustion engine 14 first runs independently of the remaining components of the drive train 10 a .
  • an overrun device 44 automatically create a coupling between the flywheels 42 , 34 , and hence, finally a coupling between the internal combustion engine 14 and the drive shaft 26 .
  • the overrun device 44 is designed such that a coupling of the flywheels 34 , 42 is created only when the internal combustion engine 14 “overtakes” the electric motor 12 , i.e., when the rotational speed of the internal combustion engine 14 is at least as great as that of the electric motor 12 .
  • overrun devices which comprise, for example, clamping bodies, ratchet wheels, toothed discs or wrap springs can be used. Which design is actually used depends, inter alia, on the expected conditions and load requirements on the drive train 10 a and the construction space available.
  • FIG. 1 also illustrates that a conventional drive train can easily be converted into the drive train 10 a . It is merely necessary to provide construction space for the motor 12 , converter 16 and battery 18 , and supplement a conventional starter element-torsion damper combination with a coupling device 46 that includes flywheels 34 , 42 and overrun device 44 .
  • a compact construction results when the machines 12 , 14 are arranged next to each other so that their rotation axes run in parallel. With this construction, the internal combustion engine 14 and the flywheels 34 , 42 and overrun device 44 are arranged coaxially.
  • the coupling device 46 is located, both physically and functionally, between the internal combustion engine 14 and the translation gear 24 .
  • FIG. 1 furthermore illustrates that the flywheel 34 has a smaller radius than the flywheel 42 .
  • the flywheel 34 can be designed more compactly, which leads to an efficiency rise on purely electric drive of the vehicle, since on acceleration of the motor vehicle only the comparatively low mass inertia of the flywheel 34 must be overcome.
  • FIG. 2 illustrates a drive train 10 b which differs from the drive train 10 a of FIG. 1 in that the electric motor 12 is connected via a second belt 32 ′ with ancillary assemblies 48 , 48 ′ in order to supply the ancillary assemblies 48 , 48 ′ with drive torque.
  • a single circulating belt can be used which connects the electric motor 12 with both the flywheel 34 and the ancillary assemblies 48 , 48 ′.
  • FIG. 3 illustrates a derivation of the drive train 10 b of FIG. 2 , in which the starter motor 40 of the drive train 10 c is not coupled with the internal combustion engine 42 via a belt drive on its side facing away from the flywheel 42 .
  • the starter motor 42 co-operates directly with the flywheel 42 in order to start the internal combustion engine 14 when required.
  • a toothed starter ring gear is provided on the flywheel 42 and engages with a gear wheel which can be driven by the starter motor 40 .
  • FIG. 4 illustrates a derivation 10 d of the drive train 10 c of FIG. 3 , in which the ancillary assemblies 48 , 48 ′ are coupled not only with the electric motor 12 but also via a connection 50 with the translation gear 24 .
  • FIG. 5 illustrates a drive train 10 e which with regard to the design of the coupling device 46 corresponds substantially to the drive trains 10 a , 10 b , 10 c and 10 d .
  • the electric motor 12 is coupled selectively with the ancillary assembly 48 via an auxiliary shaft 52 using a clutch 54 . Also the clutch 54 allows starting of the internal combustion engine 14 by the electric motor 12 .
  • FIG. 6 illustrates an embodiment of a drive train 10 f which differs from the drive train 10 e of FIG. 5 in particular in that instead of the auxiliary shaft 52 , a second output shaft 28 ′ from the electric motor 12 is provided which serves, via the clutch 54 , to start the internal combustion engine 14 or operate the ancillary assembly 48 .
  • a common feature of the respective drain trans 10 a to 10 f described hereinabove is that the advantages of an electric motor can easily be combined with the advantages of an internal combustion engine in a drive train without extensive changes to the fundamental construction of a conventional drive train being required.
  • the integration of the electric motor 12 is achieved efficiently by the coupling device 46 which also allows a reliable and efficient integration of the internal combustion engine 14 in the drive train 10 a to 10 f as soon as it has reached a suitable rotation speed. This integration takes place automatically via the overrun device 44 , minimizing the occurrence of malfunctions.
  • the drive trains 10 a to 10 f also allow purely electric drive of the motor vehicle, whereby the range of the motor vehicle depends on the capacity of the battery 18 . Also a start-stop functionality can be provided which is more comfortable and efficient than conventional systems. Also the electric motor 12 can be used directly to provide drive torque for ancillary assemblies 48 , 48 ′. In certain operating states it can also be operated as a generator to charge the battery 18 and supply the ancillary assemblies 48 , 48 ′ with electrical energy.
  • the electric motor 12 can also function as an electrodynamic brake so that the deceleration of the motor vehicle is used to generate electrical energy.
  • the internal combustion engine 14 rotates more slowly than drive shaft 26 so that the overrun device 44 ensures the decoupling of the flywheels 34 , 42 .
  • the torque of the drive shaft 26 is thus transmitted only to the electric motor 12 which converts this into electrical energy.
